Abstract

Beleuchtungsvorrichtung für Kraftfahrzeuge mit einem das Licht führenden Lichtleiter (1), der über ein Austrittskoppelelement (2) mit einem das Licht abstrahlenden Linsenkörper (3) verbunden ist, wobei die Lichteintrittsfläche (9) des Koppelelements an der Lichtaustrittsfläche des Lichtleiters anliegt und diese vollflächig bedeckt und wobei die Lichteintrittsfläche (6) des Linsenkörpers (3) an der Lichtaustrittsfläche (7,13) des Austrittskoppelelements (2) anliegt und diese vollflächig bedeckt, wobei die Lichtaustrittsfläche (7,13) des Austrittskoppelelements eine gerade waagerechte Grundseite (14) umfaßt, von der aus sich mindestens eine weitere Seite (17) stetig in Richtung der Mittelsenkrechten der Grundseite (14) erstreckt.

Figure 00000001
Lighting device for motor vehicles with a light guide (1) guiding the light, which is connected via an outlet coupling element (2) to a lens body (3) which emits the light, the light entry surface (9) of the coupling element abutting the light exit surface of the light guide and covering it over the entire surface and the light entry surface (6) of the lens body (3) abuts the light exit surface (7, 13) of the exit coupling element (2) and covers it over the entire surface, the light exit surface (7, 13) of the exit coupling element comprising a straight horizontal base side (14), from which at least one further side (17) extends continuously in the direction of the perpendicular to the base side (14).
